Key specifications
 Format: A4
 Ring mechanism: 4-ring metal
 Spine width: 35 mm (document capacity suited to moderate stacks)
 Cover color: Black
 Compatibility: Standard A4 punched paper and dividers
How to use
Open the binder rings by pulling the ring tabs or pressing the release levers, depending on the mechanism design, and insert punched A4 sheets onto the rings. Close the rings fully to secure pages and check alignment to ensure smooth turning. Use A4 dividers or sheet protectors to separate sections and distribute content evenly inside the 35 mm spine. Store the binder upright on a shelf or flat in a drawer to avoid excessive pressure on the rings and cover.
Usage recommendations
For best results, limit the number of sheets to the binder’s 35 mm capacity and distribute heavier documents across multiple binders if needed. Use standard A4 punched paper and optional dividers to maintain order and prevent overloading the rings. Keep the binder in a dry environment and avoid placing heavy objects on top to preserve ring alignment and cover condition.
